3.1 Introduction. Unusually in physics, there is no pithy phrase that sums up the study of dynamics (the way in which forces produce motion), kinematics (the motion of matter), mechanics (the study of the forces and the motion they produce), and statics (the way forces combine to produce equilibrium).
Review the units of work, energy, force, and distance. Use the equations for mechanical energy and work to show what is work and what is not. Make it clear why holding something off the ground or carrying something over a level surface is not work in the scientific sense.

φ = 90 → 0. A force does +W when it has a vector component in the same direction as the displacement, and –W when it has a vector component in the opposite direction. W=0 when it has no such vector component. Net work done by several forces = Sum of works done by individual forces.
The Cambridge Handbook of Physics Formulas comprehensively covers the major topics explored in undergraduate physics courses. It is designed to be a compact, portable, reference book suitable for everyday work, problem solving, or exam revision.
type. The amount of energy transformed (∆E) is called work W. The body losing energy does work, the body gaining energy has work done on it. Work is given by the force multiplied by the displacement through which the force acts, or: where F = force (N), d = displacement (m) KE = ½ mv2 Work = Change in Energy = Force × displacement
